22 claims. (ci. 11o-4s) The present .invention relates to incinerators and more particularly to means for preheating the material to be incinerated and to means for preheating the supporter of combustion.

Among the objects of the invention is to provide a `novel incinerator structure having a furnace .part for `the burning of fuelor the material incinerated or both, combined with means for `preheating the material to be incinerated, and to .preheat from the waste gases of combustion the air for supporting combustion of the material, with or without means for supplying heated supporter of combustion to the preheated material being incinerated as a priming of combustion there- Other'objects, advantages, capabilities, features, and the like are comprehended by the invention as will later appear and asare inherently possessed by the invention. y l

Referring to the drawings:

Fig. l is a transverse and vertical sectional view of the invention taken in planes represented by line I.-I in Fig.2 of the drawings;

' Fig. 2 is a horizontal' sectional View taken in a Vplane represented by line 2 2 in Fig. v1 of the drawings; i

Fig. 3 is a fragmentary sectional View taken in planes represented by line 3-3 in Fig. 1 of the' drawings;

Fig. 4 is a fragmentary sectionary view taken in when passing out through the ports I3, I4 and I5 to the nue I6. At the front are suitable stoking doors I8 and cleanout door I9 for chamber 9.

In each combustion chamber Il) (see Fig. 1) is a suitable grate over an ash pit 2I and located between air inlet ducts 22 having heated air inlets 23 communicating with a heated air` box 211,` and outlets 25 leading to the ash pits 2| and controlled by suitable damper-valves 26. At the rear of the grate 20 is a tuyre construction 21 which is inclined and is provided with ducts having at their lower ends outlets 28, and having their upper ends supported on suitable arches 29 in the chambers .Leading into the upper `ends of the tuyres2'l areheated air ducts 30 supported at the forward ends in .the rear end of thetuyresl and at the rear ends in the portion 3l of the rear Wall 2, these ducts 30 having communication with an air chamber or box 32 having an inlet 33 from any suitableA l with apertures 35 and 3B for passage of some of alo `planes represented by line 4-4 in Fig. 1 of the drawings; and,

Fig. 5 is a fragmentary` vertical and transverse sectional view similar to Fig. 1 of an alternative formof device.`

Referring more4 in detail to the drawings,`the` `embodiments selected to illustrate the invention are shown in the. form of a furnace comprising `a base structure I, al rear Vwall structure 2, a front `wall structure 3, a suitable top wall structure 4,

side wall structures and E with intermediate wall structures 'I and `8 providing lbetween them chambers I9 and I0, of which the chambers IIJ constitute i `combustion chambers.

`The products of combustion pass from the outer to the `inrierchambers "I0 by way of a port or door I I .provided in the wall "1 between the chambers I0,

"and thence with the products of combustion of the inner `chamber Il) by way of the port or door I2 into chamber 9, thence by way `of ports or doors I3, 'M and 15 respectively in walls `8, 'l and E, to flow out by wayof a iiue `lli leading t0 a suitable stack i (not shown).

At the rear of each chamber I0 is a preheatiner chamber 11 through which the hot gases flow the heated air from the tuyres 21 to assist in the combustion or incinerating of the material sliding down over the surface or wall 34.

The tuyres 2l and the ducts3ll are so exposed to the hot gases passing through the chamber Il as to absorb heat therefrom and to heat the air passing through the ducts 30 and the `tuyres 2l. Likewise some of the -heat of the hot gases inthe chamber Il passes through the wall 31 of the airi box 24 to also heat the air passing through the air box'24 to the ducts 22. i

At the top of each chamber Il is a metal cover or platform 33 to form a closure for the chamber Il and to receive and heat the waste material to be incinerated. The hot gases passing through the chamber Il heat theplatform 38 so as toY preheat such material. The material is charged onto the platform 38 by way of a chute 39 above the platform. i

For the purpose of regulably feeding the material piled upon the platform 33 any suitable means may be used, such as a feed screw 40 as shown in Fig. l, or a pusher 4I as shown in Fig. 5, or any other suitable means. The feed screw 40 is `rotatably supported by way of a shaft 42 ro` ltatable in suitable bearing means 43 carried by the frame M set in the wall 2, and is operated by .any suitable power source (not shown).

i 1n Fig. 5 the pusher 4I reciprocates in a collar 45 set in the wall 2 and by way of a track means 45 riding on rollers 4l carried on supports 48V on the base of the collar 45 and a top 49 of a frame structure 5t at the rear of the wall 2. Operation of the pusher is effected by means of a link 5| articulated to a lug 52 secured to the pusher 4| and pivotally connected to a crank 53 operatively connected to a wheel 54 driven by a belt 55 in turn driven by a suitable motor 56 mounted on apedestal 51.

Referring to Fig. 4, it will be noted that the ducts 22 have inclined walls 58 for preventing the piling up of material on the top of the duct 22 and to guide the material down to the grate 20,-

In use the material to be incinerated is chargedV down through the chute 39 onto the platform 38. This platform is heated by waste gases as above described so that the material is preheated. The material is then gradually fed by means of the feed screw 40 or the pusher 4| to move down over the inclined wall 34 of the tuyres, and thence onto the grate 2li. The re on the grate 20 will consume some of the material as it moves down the wall 34 and onto the grate 20.

The products of combustion pass through the ports or doors in the side walls of the combustion chambers and proceed into the chamber 9. From this latter chamber the hot gases pass through the chamber il and preheat the tubes 30, the tuyres 2l, as well as the air box 3l. This heat hits the air passing through the air tubes 30 and the tuyres 2l. The air is introduced by way of the inlets- 33 and the air boxes 32. From the air box `24 the heated air passes through the ducts 22 and thence by way of the ports 25 into the ash pits 2l beneath the grates 20. `Thus heated air supports combustion on the grates. By reason of the platform 38 being heated the material to be incinerated is thus preheated so that further in- 36 provide a means for the introduction of the heated air into the mass on the wall 34 so as to effect what might be called a prime combustion or burning of the material.

While I have herein described andl upon the drawings shown a few embodiments of the invention, 'it is to be understood that the invention is not limited thereto but comprehends other constructions, arrangements of parts, details, and features, without departing from the spirit of the invention.
